Mobile Agents for CPS in Intelligent Transportation Systems

Abstract

Recently, cyber-physical systems (CPS) have emerged as a promising direction to enrich the interactions between physical and virtual worlds. Because of the large-scale features of CPS, mobile agents (MA) technology can promote the performance of CPS. In this article, we first introduce the concept and characteristics of CPS, MA, and intelligent transportation system (ITS). Then, we propose the structure of intelligent transportation CPS (ITCPS). On this basis, giving the case of mobile agents for ITCPS, we exploit a mobile agent by three levels (node level, task level, and combined task level) to reduce the information redundancy and communication overhead. Finally, we in brief outline the technical challenges for ITCPS.

The integration of CPS, CPSS, and ITS: A focus on data

“…CPS-ITS is expected to address numerous challenges faced by travelers and traffic operators by means of reliable real-time traffic data [35,36] . Realtime data is crucial in many transportation applications, such as blind-spot warnings during lane changing, and crash avoidance warnings during car following [37] . Distributed sensors, rapid communication networks, and the powerful cloud computing platforms in CPS-ITS guarantee real-time collection, transmission, and effective feedback of massive data.…”
